摘要:
It is known to oscillate hollow processing drums to increase the agitation of the processing solution within the drum. However, these drums require a relatively large amount of processing solution to operate effectively, and are therefore unsuitable for unstable and/or single use processing chemistry. Described herein is a drum arrangement (10) in which a drum (14) oscillates within a generally U-shaped vessel (12), a processing tank (18) being defined between the drum (14) and the vessel (12). Photographic material (30) is driven through the tank (18) by a pair of drive rollers (24, 26) situated at the inlet (28) to the tank (18). The drum (14) is oscillated through an angle between 5° and 90° for effective processing.

Ein farbfotografisches Entwicklungsverfahren für Materialien mit hohem AgCl-Anteil, das unter standardisierten Bedingungen der Entwicklungszeit, -temperatur und des pH-Wertes ohne Qualitätsverlust eine Reduktion der Entwicklersubstanz-Konzentration gestattet, wird so durchgeführt, daß im Entwicklungsbad unter Flüssigkeitsniveau die emulsionsseitig adhärierende Diffusionsschicht wenigstens einmal deutlich verringert oder gänzlich entfernt wird.
摘要:
Lors de l'utilisation de solutions de traitement instables, des taux de remise en circulation et/ou de régénération élevés peuvent être requis, ce qui risque de produire un traitement non-uniforme du matériau photographique dans l'appareil de traitement photographique utilisant de telles solutions. L'invention décrit un appareil dans lequel des éléments agitateurs (17) sont placés dans la cuve de traitement photographique. Ces éléments (17) sont fixés à une paroi (11) de la cuve en un point (18). L'élément (17) comporte une extrémité libre (25) qui est disposée de façon à reposer contre une surface d'émulsion (26) du matériau (20) en cours de traitement photographique (ou contre une surface de paroi interne (19) en l'absence de matériau à traiter (20). Au fur et à mesure que le matériau photographique (20) avance le long de la voie de traitement (13), il se produit une agitation de la solution de traitement photographique dès lors qu'une partie de cette solution passe sous l'élément (17), le reste passant à travers l'élément (17) lui-même.
摘要:
A defoaming device for aeration, for use in a processor equipped with an aeration apparatus (30) for sending air into a processing solution. The defoaming device includes a pipe (66) for guiding foam produced in the aeration apparatus to outside the aeration apparatus; and at least one of a throttle portion (68), which is disposed midway in the pipe and formed by reducing a cross-sectional area of the pipe, and an air-stream guiding device for guiding an air stream into a portion of the pipe in a downstream direction corresponding to the direction of the flow of the foam. The flow rate of foam in the pipe is accelerated by the throttle portion and/or the air-stream guiding device, thereby positively removing the foam produced in the aeration apparatus.
摘要:
Die Vorrichtung zum Entwickeln von fotografischen Schichtträgern weist mehrere Behälter mit Behandlungsflüssigkeit auf, wobei an jedem Behälter eine von außen antreibbare Pumpe (13) zur Umpumpung der Behandlungsflüssigkeit vorgesehen ist. Der Boden (1a) des Behälters (1) ist durch eine besondere Formgebung in die Pumpe (13) integriert, wobei der Boden (1a) eine nach außen gerichtete Zylinderform (1d) bildet. Der Zylinder (1d) wird von außen her von einem Ringmagneten (15) umgeben, der auf einen mit einem Rotationskörper (10) der Pumpe verbundenen Magneten (11) im Inneren des Zylinders wirkt. Damit entfallen Abdichtprobleme von durch die Behälterwand durchgeführten Elementen.
摘要:
A photo-finishing apparatus for a silver halide photosensitive material, including an agitating device to agitate or circulate a processing solution in a processing tank, a time detecting device to detect an elapsed time since a processing operation was completed, a temperature detecting device to detect temperature of the processing solution in the processing tank, and a control section to control operation of the agitating device by such ways that when the time detecting device detects a predetermined elapsed time, the control section deactivates the agitating device, and when the temperature detecting device detects that the temperature of the processing solution in the processing tank has dropped lower than a predetermined lower limit temperature, the control section re-activates the agitating device, and continues to activate until the temperature detecting device detects that the temperature of the processing solution in the processing tank has increased to a predetermined acceptable processing temperature.
摘要:
A method of processing photographic material in which a reciprocable member is plunged into a tank containing a small volume of processing solution. The solution is rapidly displaced through the channels created between the tank wall and the plunger and across the surface of the photographic material.
